2. Definition and Key Features
Definition of NGN
Definitionof NGN(DraftRec.
Y.2001)
A NGN is a packet-based network able to provide Telecommunication services and able to make use of multiple broadband,
QoS-enabled transport technologies and in which service-related functions are independent from underlying transport-related technologies.
It enables unfettered access for users to networks and to competing service providers and/or services of their choice.
It supports generalized mobility which will allow consistent and ubiquitous provision of services to users.

Key Features of NGNPacket-based transfer;Separation of control functions among BC, call/session, and application/ service;Decoupling of service provision from transport;Support for a wide range of services based on service building blocks;Broadband capabilities with end-to-end QoS;Interworking with legacy networks via open interfaces;Generalized mobility;Unrestricted access by users to different service providers;A variety of identification schemes;Unified service characteristics for the same service as perceived by the user;Converged services between fixed/mobile;Independence of service-related functions from underlyingtransport technologies;Support of multiple last mile technologies;Compliant with all regulatory requirements (e.g. emergency, privacy, lawful interception, etc.)

General QoS Requirements of NGNTwo perspectives for NGN QoS
“Vertical” mechanism : linking the upper and lower layerQoS mechanisms (e.g. diffserv, etc)“Horizontal” mechanism : linking the lower layer QoS control between different domains and networks.
Considerations for NGN QoSEnd-to-end QoS class definition for telephonyover packet networks;End-to-end multimedia QoS class definition framework anda method of Identifying QoS classes of individual media components;Specification of how to use lower layer QoS mechanism to achieve Upper layer QoS within the network;Inter-domain lower layer QoS control;End user perception of QoS.

Provide QoS control (inc. Res. reservation, Admi. control and Gate control), NAPTand/or FW traversal control func. over access and core transport networks.Admission control involves checking authorisation based on user profiles, SLAs, operator specific policy rules, and resource availability within access & core transport.Act as the arbitrator for resource negotiation and allocation between Application Functions and Transport Functions.

7. Conclusion
Impacts to Policy and Regulation base
• NGN provide a platform separating Services with Transport• Politics and Regulation environment would be impacted with this• Current Vertical environment would be changed to Horizontal env.

7. Conclusion
Standards for Near Generation, not Next
NGN stands for Next Generation, but targeted for Near GenerationNGN could be value added framework for all players : Users, Operators, Providers and Regulators etc.NGN could be evolved from Current Generation NetworkNGN could be basement for making convergence world(real Telecommunication World)NGN Standards could be Globalize rather than Localize boosting global village and shorten digital divideITU-T could be centre of NGN standards
